' Specification of letters Patent.

Patented Nov. 12,1912,

Application filed July 11, 1912. Serial No. 708,823.

To all whom "it may concern:

Be it known that 1, Jesse I. Boron, a citizen of the United States, and a resident of the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in SuganMiHs, of which the following is a specification.

My invention relates particularly to sugar cane mills and consists in improved means for supporting the triangularly" arranged rolls in properly adjusted relative positions, and for adjustably setting the guiding turn plate in proper position relative to the adjusted rolls, as fully described in connection with the accompanying drawings, the novel :Eeatures bcing specifically pointed out in the claims.

Figure 1 is an inside elevation of one of the pair of housings of a sugar mill having my nventionapplied thereto; the turn plate bein shown in cross-scction on the line 11 of Fig. 2, and the rolls in cross-section through their journal-bearing ends, the working faces of the latter being indicated by dotted circles. Fig. 2 is mainly a front or edge view of one of the housings, showing the turn plate mounting therein and the setting mechanism for said turn plate; the housing being partly in section on the line 2-2 of Fig. 1. Fig. 3 is a plan view of the top housing cap. Fig. 4 is a fragmentary outside elevation of the housing showing the adjustable mounting oi the turn plate pivot bar. Fig. 5 indicates a modified mounting of the turn plate upon the housno As is well known in sugar cane mill con struction, the triangularly arranged upper roll 5 and lower rolls 6, 6, have thelr reduced journal ends 8 mounted in similar end housings 9, in such manner as to permit of properly adjusting the lower rolls relative to the upper one, and so as to permit of a yielding movement of the upper roll as required to avoid possible undue strains. The partially crushed cane is transferred from the front lower roll to the rear one by means of a turn-plate which is carried by the housings and is adapted to be set into proper operative relation to the adjusted rolls. My improvements provide a simple and advantageous manstruction involving these well known general features, the main objects.

being to facilitate construction and the making of repairs and operating adjustments, and rat the same time insure requisite strength to safely withstand the great strains incident to operation.

The journal .boX or bearing 11 of the upper roll is backed by a hydraulic plunger so as to permit of the raising of the roll in the journal box recess 12 of the h0using when it is subjected to undue strains as stated; these strains being transmitted to the upper cap 13 of the housing, as indicated, through a plungcr plug 14: which is removably secured to-the cap as more fully shown in Patent No. 976,14 l, issued to me November 22nd, 1910. In my present construction this cap 13 is directly secured to the housing, being provided on its under side with looking cars 15 which are adapted to be set into or out of engagement with locking-lug extensions 16 provided, on the housing, by a partial turning of the cap in reverse directions; the cap being normally retained in locked position, as shown, by means of relatively small bolts 17 the reinovaloi' which permits of the cap itself being readily disengaged or removed, though the removal of the plunger plug 14 only is required for ordinary repairs.

Each of the lower rolls 6, 6 has its reduced ends 8 journaled in bearing boxes 20, which are slidablein inclined ways formed int-he inner portion of the journal box recesses 21 ofithe respective, housings. Each of these recesses opens horizontally, at the front and rear or the housings respectively, and is formed with one wall, 22, of said inclined way, while the opposite wall 23 of said way is formed by an inward extension 25 on the .vertically arranged lower housing cap 26. Each cap 26 is rigidly secured to the hous ing, as shown, by means of keys 27, 28;

and each is provided with an adjusting "block 32, which forms an adjustable backing forfthe bearing box 20, it being fo'rcibly moved inward. by the adjusting screw 30 to raise the roll as required, and eing conveniently withdrawn to lower the roll, as indicated by operating a nut 33 on the end of a fixed extension 34 on thewedge which passes through the cap. f T

"lower rolls 6, 6 being locate The construction described ermits of the as close together as possible, which is advantageous because it reduces the distance which the canemust be carried by the turn plate mechanism hereinafter referred to, in transferring it from the front to the rear roll,

and also because the lines of strain through,

the roll axes are brought nearer to the vertical. In my improved construction the lateral strains are easily carried by the lower housing caps 26, and the adjustment of the rolls is conveniently effected, while at the same'ktime the construction and assembling of the machine is facilitated.

The turn plate device which I employ comprises a turn plate 40, and a rest bar or web plate 41 therefor, both extending between thehousings as usual. The device is adjustably mounted upon the latter, andalso arranged to be swung forward or rear ward, so as to provide for accurately locating the plate 40 relative to the three rolls. In my preferred construction shown, the lower-edge of the rest bar41 is pivotally connected at 43 to a separate pivot bar 44, the squared ends 45 of which latter are extended through housing openings 46, in

which they are adjustably secured to the housing. This adjustment is provided for, as shown, by bottom plates 4'1 1n said open.-

, ing, upon which the bar rests and which their adjacent ends 58, 58 arranged in en-' gagement with an end lug 59 on the turn plate device, while their oppositely extended ends are connected to the housing so as to permit of their being accurately adjust- .ed-to swing-and hold the device as desired. These connections consist of an adjustmg link 60 which is pivoted to the housing at 61 and upon whichv one of said levers is engaged so as to be moved thereon by means of an adjusting nut 62; and a similar link 63 for the other lever, pivoted to the hous- 4 ing at 64 and upon which said lever is en gaged' so as to be yieldingly pressed into action by a spring 65. By operating the adjusting nut 62 in one direction or the other the lovers are jointly operated so 'as to set the plate 40 forward or backward as required; which adjustment, in connectlon with the separate adjustment of the pivot bar 44 previously described, enables the plate 40 to be, conveniently set with the nicety required to insure proper feeding of the material.

The preferred construction specifically described may be readily modified Without departing from the invention as defined in the'subjoined claims. In Fig. 5 for instance the pivoted turn-plate device is shown as adjustably mounted upon inwardly extending housing brackets 65, the adjustment of the pivotal axis provided for in such case being less conveniently effected than in the preferred construction as it does not permit of free access from outside the housings, but the setting mechanism employed being otherwise the same.
